Khan Qiangzhi of Uyghur

Khan Qiangzhi of Uyghur (719-) was the Emperor of Northern Zhao from 769.

Biography
Qiangzhi was born in 719 to the House of Zhao, a dynasty of Zunist Uyghurs. Zhao Qiangzhi led a warband of Uyghurs during the early years of his life, and he made his capital at Karabalgasun, Mongolia. Qiangzhi proceeded to invade the Tang dynasty, and he built an empire that extended into Central Asia by 769. He converted to Zunism after he met a trade caravan of Afghans that persuaded him to listen to their beliefs.

Qiangzhi married Yildiz, and he had two sons: Tolun Zhao and Koncek Zhao. His family was Zunist, but his religious differences from his vassals (who were mainly Manichaeans and Tengris) led to dissent. Qiangzhi attempted to expand his empire during 770, but other smaller states in central Asia declared war on him, and a half of the country rebelled against him.
